Dear grass devs, JFYI, i have updated the vtkGRASSBridge to work only with grass7 and added vector support without topology handling.
The vtkGRASSBridge is hosted on code.google.com as svn repository: http://code.google.com/p/vtk-grass-bridge/ Here a small python example to triangulate vector points from the nc demo data set with the VTK delaunay filter class: # The purpose of this example is # to read a grass vector map without topology information # into the VTK poly data format and processing that map with vtkDelaunay2D. # The processed data is written as VTK XML file to the file system # Init grass variables init = vtkGRASSInit() # Now build the pipeline # read the vector map without creating topology reader = vtkGRASSVectorPolyDataReader() # The reader does not need topology information reader.SetVectorName("elev_lid792_randpts") # Setup the delaunay triangulation delaunay = vtkDelaunay2D() delaunay.SetInputConnection(reader.GetOutputPort()) # write the data as XML with base64 encoding writer = vtkXMLPolyDataWriter() writer.SetFileName("/tmp/test.vtk") writer.SetInputConnection(delaunay.GetOutputPort()) writer.Write() Have fun Soeren _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
